ABSTRACT:
An articulated connector for providing electrical insulation between downhole well equipment such as logging sondes suspended by a wireline. Articulated joints are connected to the well equipment to provide for the desired movement, and the joints are connected by a central housing. The housing is configured so that a nonconductive element interrupts electrical conductivity through metallic components of the housing. The housing uniquely combines with the articulated joints to provide an articulated connection between the well equipment while providing electrical insulation therebetween.
